UnmarshalKey: Using "y" variable in yml stays empty

[maltegrosse]

Expected behavior (what you expected to happen):
By using a yaml file with an array and 3 fields, e.g.

---
genres:
  - genre: soul
    x: 703
    y: 15128
  - genre: pop
    x: 1150
    y: 13682

and creating a struct

type Genre struct {
	Genre string `mapstructure:"genre"`
	Y int `mapstructure:"y"`
	X int `mapstructure:"x"`

}
var Genres []Genre

viper.UnmarshalKey("genres", &Genres)

should fill the structs with string genre,int x and y.

Actual behavior (what actually happened):
Field Y stays empty. X is filled with a value.

Workaround:

Rename yaml field to any other variable, e.g. mm and use in struct: Y int `mapstructure:"mm"`

Environment:

• Viper version: v1.7.1
• Config source: file
• File format: YAML

go-yaml/yaml#740
In YAML 1.1, scalars like y and Y are resolved as booleans, change to this,

---
genres:
  - genre: soul
    x: 703
    'y': 15128
  - genre: pop
    x: 1150
    'y': 13682

Thanks @xwjdsh !

Closing as it's working as expected.
